I guess that's why mine came with 4 batteries in the box. No battery issues for me so far, but it's only been a couple of weeks. To be honest, I'm O.K. with removing the battery, since I do that anyway. It just amazes me how they can pack all this utility into such a small package.
As a follow-up, I also got to try out a prototype sample of the new incident meter that can clip onto your hand. I've been thinking about that a bit, and what I don't like is the fact that the dome is fixed in position relative to the display. This can make it awkward to take measurements when your shadow is over the dome. Since you can't reposition the dome relative to the display, it may not be easy to see the display when you take a reading with the dome in the desired position. In that respect, I think it's actually less useful than a conventional Minolta, Sekonic, or Gossen incident meter. It's smaller than a Minolta/Sekonic/Gossen, but not small enough to make it any more convenient, in my opinion. The real advantage of the Revini is the colour temperature feature, which isn't available in the other incident meters, but not something most people really need. The dilemma here is that you can get a good used Minolta/Sekonic/Gossen incident meter for around $100, so that's pretty tough competition for the Reveni. For me, the prototype didn't offer a clear advantage over what I already have, or what I could buy instead.
